METHOD OF PRODUCING BODIES 01R SMALL PARTICLES OF SUBSTANCES.

To all whom it may concern Be it known that I, ERIKA MORE, a citizen of Switzerland, residing'at Hardturmstrasse 78, Zurich, III, Switzerland, have invented certain new and useful Improvements in Methods of Producing Bodies or Small P31- 6- clare the following to be a 'full, clea'r, and

exact description of the invention, such as will enable others skilled in the art to which.

it appertains to make and use the same, reference being had to the accompanying drawings,and to letters or figures of reference marked thereon, which form a part of this specification; 1

The present invention relates toamethod according to which glass or other substances hereinafter, referred to, pre'ferably in the form of rod or wire, is melted, divided and thrown onto a surface under considerable pressure, whereby cohesive coatings of any desired thickness are produced.

The principle'of the invention consists in confining the quantity of material melted to that amount which is thrown on'; for instance the end of a glass rod is melted successively by a blow pipe flame in any suitable manner or otherwise as hereinafter de-' scribed, and the molten drops of glass formed thereby are simultaneously thrown onto the aforesaid surface by means of compressed air, steam'or compressed gases,

Figure l is a' diagrammatical view of the operation. Fig. 2 is aview of a modification and Fig. 3 is a-further' modification.

a is a glass rod which is fed forward uniformly'or' intermittently in the guide "sleeve b,"the lower' end of said rod being melted away by a flame 0; The dropsbf'molten glass rapidly formed in succession thereby are driven with great 'forceby a special conveying blast, from the pipe 'zfonto'a preferably heated surface 6, whereby mutually united and welded coats-of lazing of an amorphous structure are formed. The glass'rod' may also be melted by'me'ans of a blow flame concentrically surrounding such rod, the molten drops of glass formed thereby being thrown onto the: surface -by the pressure of the fiame,'assistedif neces-.

and oxid of lead glass) and highly compressed and heated air effects a more or less fine disintegration of the molten drops of glass.

' Fig. 2 shows the operation with a concentrically fed flame, which is moved forward in the pipe 6 at a uniform speed. Between the two pipes b and a there is a hollow space 03 through which is fed a combustible gas or gas mixture (for example, lighting gas, oXy-hydrogen gas, acetylene) the compressed air re, qulred for the disintegration and throwing on operation issues through the hollow space fbetweenthe pipes c and 6.

"It will'be obvious that the size, pressure of gas, chemical natureof the flame and composition of the material to be melted are ofgreat importance for obtaining the most favorable effects; it is also necessary that the other factors, such as the thickness of glass rod, the speed at which the rod is fed forward, .the quantity, temperature and pressure of the conveying blast, as well as the distance of the surface to be coated from the blow-apparatus,'should be in a certain relative ratio, which can be readily ascertained by experiments. The glass may also be melted by electrical means, as for instance with the aid of the device shown in Fig. 3, or by directing an are light by magnetic action toward the end of the glass rod. a is the glass rod which is fed downward in the graphite tube 6 which simultaneously a being the glass rod such manner that only the lowest part of the tube 6 is rendered incandescent andconsequently only the lowest part of the glass rodis melted. Instead of melting away the glass in' the form of a thin rod-{the material to'b'e. melted ma also be fed:to the hollow space in the tube 6, in the form of granules or flexible cables. e

d" is' the duct for the preferably heated conveying blastf In order to localize as far as-possible the heating ofthe sleeve electr'ode b, the latter is preferably provided with a thick coating of copper reaching to the line e,- to this end the electrode 7) may al'sp be reduced in cross section at its lower en Inversely, the material to be melted may be fixed in position and the melting and throwing on device may be movably arranged. The latter may for lnstance be ar ranged so that with two nozzles arranged one above the other, a hot blow flame issues from the upper one while the lower one effects the throwing on operation.

The coats may be permanently or detachably applied resulting in the latter case in the production of self-formed bodies. Vhen stead of glass.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to'be performed, I declare that what I claim is:
